COMFORTBOARD™ 110

COMFORTBOARD™ 110 is a rigid, high density, non-combustible, stone wool insulation board designed for use as an exterior continuous insulation in commercial applications. COMFORTBOARD™ 110 is a thermally efficient, moisture resistant, vapor permeable board and takes the place of other external sheathing insulations to create high-performance wall assemblies that are effective against fire, moisture and thermal bridging, and allow for superior drying potential.

  • Vapor Permeable
  • Fire resistant, non-combustible product with a melting point of approximately 2150°F (1177°C)
  • Environmentally Sustainable
  • Moisture Resistant
  • Stable Long-Term R-Value
  • Dimensionally Stable
  • UV Resistant
  • Sound Absorbent
  • ROXUL can contribute to earning LEED® points
